Product details
Overview
BAS12505WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOT323 package configured as a common-anode dual diode pair, rated for 25 V reverse voltage, 100 mA forward current, and 250 mW total power dissipation at TS ≤ 76°C, used for bias isolation and clamping in automotive metering circuits compliant with AEC-Q101.
For engineers reviewing the BAS12505WE6327HTSA1 datasheet, BAS12505WE6327HTSA1 pinout, BAS12505WE6327HTSA1 application, or BAS12505WE6327HTSA1 equivalent, key selection criteria include forward voltage matching (≤20 mV at 10 mA), low diode capacitance (1.1 pF at 0 V), differential forward resistance (15 Ω at 5 mA), and thermal resistance (RthJS ≤ 295 K/W).
Technical Context
This dual-diode device integrates a diffused guard ring to enhance reverse leakage control and ESD robustness. Its common-anode configuration enables simultaneous clamping of two signal paths with matched VF characteristics, critical for precision analog front-ends in automotive instrumentation.
Designed for AEC-Q101 qualification, it operates across –55 °C to 150 °C junction temperature range and supports pulsed forward currents up to 500 mA (non-repetitive) while maintaining low forward voltage (400–650 mV typ. at 10 mA) and minimal capacitance variation over 0–20 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 25 V - Maximum blocking capability for signal-level clamp protection without breakdown |
| Forward Current (IF) | 100 mA DC - Continuous conduction rating for bias and isolation in low-power analog rails |
| Forward Voltage (VF) | 400–650 mV @ 10 mA - Enables low-loss signal steering with minimal voltage drop penalty |
| Diode Capacitance (CT) | 1.1 pF @ 0 V, 1 MHz - Preserves high-frequency signal integrity in RF-adjacent metering circuits |
| Thermal Resistance (RthJS) | ≤295 K/W - Supports reliable operation at TS ≤ 76°C in compact SOT323 PCB layouts |
| VF Matching (∆VF) | ≤20 mV @ 10 mA - Ensures balanced clamping thresholds between dual anodes for differential sensing |
| Junction Temp (Tj) | 150 °C - Validated for under-hood automotive environments per AEC-Q101 stress testing |

Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual configuration | Enables symmetrical clamping of two independent analog inputs to a shared reference without discrete component duplication |
| Low VF matching (≤20 mV) | Reduces offset error in differential sensor interfaces where both diodes conduct simultaneously |
| Integrated diffused guard ring | Suppresses edge leakage and improves VR stability under high humidity or contamination conditions |
| AEC-Q101 qualified | Validated for automotive applications including instrument clusters, battery monitoring, and body control modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode pair applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Single diode, SOD-323, 30 V VR, 500 mA IF, no VF matching spec | Lacks dual configuration and VF matching; requires two devices for same function | Use only when board space allows discrete duplication and matching is non-critical |
| NSR20F30NXT5G | Dual common-cathode, SOT-23, 30 V VR, 200 mA IF, VF = 450 mV typ. @ 10 mA | Opposite polarity configuration; higher IF rating but no AEC-Q101 qualification | Select for industrial non-automotive use where higher surge current is prioritized over automotive reliability |
Compared with RB050M-30TR and NSR20F30NXT5G, BAS12505WE6327HTSA1 uniquely delivers AEC-Q101-qualified common-anode topology with guaranteed VF matching-enabling single-component, space-efficient, and metrologically stable clamping in safety-critical automotive analog subsystems.

FAQ
What is the maximum allowable soldering temperature for BAS12505WE6327HTSA1?
The SOT323 package is rated for standard lead-free reflow profiles with peak temperature up to 260 °C for ≤30 seconds, consistent with IPC/JEDEC J-STD-020D. Preheat and soak zones must comply with ramp rates ≤3 °C/s to prevent package cracking or delamination.
Does BAS12505WE6327HTSA1 support bidirectional ESD protection?
No-it functions as a unidirectional clamp due to its common-anode Schottky structure. For bidirectional protection, external series resistors and complementary cathode-connected diodes are required; the device itself clamps positive transients to VCC and negative transients to ground only when biased accordingly.
How does the diffused guard ring improve performance in humid environments?
The integrated diffused guard ring reduces surface leakage current by controlling electric field distribution at the silicon periphery, lowering IR to ≤100 nA at 20 V even after 85 °C/85% RH preconditioning-critical for long-term reliability in automotive cabin and under-hood modules.
Can BAS12505WE6327HTSA1 replace BAS125-04W in existing designs?
Yes-BAS12505WE6327HTSA1 corresponds directly to the BAS125-05W variant (common-anode SOT323), sharing identical electrical specs, thermal limits (TS ≤ 76°C), marking "15s", and AEC-Q101 qualification; no layout or firmware changes are needed for drop-in replacement.
